The aim of this study was to measure changes in the cross-sectional area of the spinal canal and the area of the intervertebral foramen for each pedicle segment before and after the pedicle extension using computer-simulated transpedicular osteotomy to provide a theoretical basis for clinical decompression in the lumbar spinal canal. Using spiral CT scanning of the original lumbar spine, a fini...

Degenerative lumbar spinal stenosis is the most common indication for lumbar spine surgery in adults over the age of 65. Although some studies have claimed improvement with conservative treatment, several comparative studies have shown better outcomes for surgical treatment for patients with moderate to severe stenosis. As the life expectancy of the elderly population increases, and by virtue o...

background : lumbar degenerative spondylolisthesis (lds) is a degenerative slippage of the lumbar vertebrae. we aimed to evaluate the surgical outcome of degenerative spondylolisthesis with neural decompression, pedicular screw fixation, reduction, and posterolateral fusion. methods : this before-after study was carried out on 45 patients (37 female and 8 male) with lds operated from august 200...

BACKGROUND Trans-sacral epiduroscopic lumbar decompression (SELD) is an emerging procedure for the treatment of lumbar disc herniation (LDH), with favorable outcomes having been reported. However, the complications associated with SELD have not been comprehensively evaluated to date. Therefore, the aim of our study was to describe the incidence rate, types, and characteristics of complications ...

OBJECTIVE We have conducted a prospective study to evaluate the results and effectiveness of bilateral decompression via a unilateral laminectomy in 50 patients with 98 levels of degenerative lumbar spinal stenosis without instability. METHODS Clinical outcomes were assessed using the Visual Analog Scale, Oswestry Disability Index, Short Form-36, and subjective Satisfaction Measurement. RES...

[Purpose] To examine the variations in the lumbopelvic rhythm and lumbar-hip ratio in the frontal plane. [Subjects and Methods] Markers were placed on the T10 and T12 spinous processes, bilateral paravertebral muscles at the T11 level, the pelvis, and the femur. Lumbar spine and hip angles were measured during lateral trunk bending using three-dimensional motion analysis. Data from the trunk la...

OBJECTIVE The purpose of this study was to evaluate the outcome of endoscopic decompression surgery for intraforaminal and extraforaminal nerve root compression in the lumbar spine. METHODS The records from seventeen consecutive patients treated with endoscopic posterior decompression without fusion for intaforaminal and extraforaminal nerve root compression in the lumbar spine (7 males and 1...

BACKGROUND Laminectomy/laminotomy and foraminotomy are well established surgical techniques for treatment of symptomatic lumbar spinal stenosis. However, these procedures have significant limitations, including limited access to lateral and foraminal compression and postoperative instability. The purpose of this cadaver study was to compare bone, ligament, and soft tissue morphology following l...

Cauda equina syndrome is a well described state of neurologic compromise due to lumbosacral root compression. In most cases, it is due to a herniated disc, tumor, infection, or hematoma. We report a case of rapid lumbar synovial cyst expansion leading to acute cauda equina syndrome and compare it to similar cases in the literature. The patient is a 49-year-old woman with a history of chronic l...
